In February, we announced early data points about the traffic that Facebook was delivering to mobile apps and games. Over the past two month, the traffic we drive to mobile apps continues to rapidly grow:

Facebook sent more than 160 million visitors last month to mobile apps (up from 60 million in late February).

These mobile visitors were responsible for more than 1.1 billion visits to mobile apps in the same time frame (up from 320 million in late February).

Seven of the top ten grossing iOS apps and six of the top ten grossing Android apps are integrated with Facebook.

As mentioned in previoushighlights, features like Single Sign On and Open Graph increase installs, usage, and re-engagement for mobile apps, regardless of whether they are built for iOS, Android or the mobile web.

Here are a few examples of mobile apps finding success using Facebook to drive growth:
